摘要: Abstract Batch drying was performed in the pulsed fluidized bed with various species of biomass particles as an indicator gas–solid contact efficiency and mass transfer rate under different operating conditions including pulsation duty cycle particle size distribution. The fluidization cohesive benefited from shorter opening time gas flow increased peak pressure drop. presence fines enhanced large irregular particles, well efficiency. A model based on two-phase theory proposed, which effective diffusivity calculated for rates, temperature frequency. Intricate relationship discovered between frequency diffusivity, deeply connected hydrodynamics. Effective also found to be proportional temperature. Operating near natural system favored transfer.
